This section lists the relevant statutory requirements under 42 U.S.C. 6295(hh) ( i.e.

, section 325( hh ) of EPCA, as amended by the Energy Independence and Security Act of 2007 ) that apply to metal halide lamp fixtures

. On December 19, 2007, the President signed into law the Energy Independence and Security Act of 2007 (EISA 2007) (P.L. 110
